Analysis

Pilot was reported missing aprx 4 days after he had departed for madeline island. An air search was not successful in locating the airplane and pilot. About 3 months later, on 11/17/90, the wreckage was found. The airplane had impacted the ground at a high impact angle and at a high impact speed. The pilot's wife told investigators that he 'loved to go to madeline island and drink.' Witnesses reported that the pilot was last seen in a bar at 0100 CDT, and that he appeared to be quite intoxicated. The pilot asked several people for a ride to the airport, but none recalled seeing him leave the bar. The airplane was not observed at the madeline island airport later that morning. The pilot's medical certificate had a limitation against night flying due to color blindness and required corrective lenses for near vision. There were no glasses located in the wreckage.
